Fluid nozzle with directional outlet jet of continuously changing direction

摘要

A nozzle discharging a continuously changing direction stream of gas, liquid or mixture thereof, particularly for use in hydrotherapy, e.g. in awhirlpool bath, is controllable to adjust the discharge pattern and is a development of the nozzle of GB 2089684. The nozzle comprises a body (412), a rotor chamber (450) coaxial within the body and a rotor body (480), fed by gas and liquid inlets, within the chamber; a control knob (490) is rotatably attached to the rotor body to control the flow. A slidable shroud ring (493) fits over a connector knob (490) within the chamber. The speed of rotation of the rotor body is altered by screwing the control knob to alter the position of inclined offset ports (496), which may be partly closed by the shroud ring. Ball-bearings (485) may support the rotor body in a position protected from dirt.
